Abstract
A sensor arrangement and method for an inductively rotational sensor consisting of a remote clone coil connected to a processor. The clone coil is located between a proximity sensor including a sensor and a rotating target so that when in an input or interrogatory mode rotational speed of the targets on a rotatable body is detected by the clone coil as a base rotational speed. The processor and the clone coil in an injection or output mode presenting emulating pulses to the sensor to mask the normal sensor coil to target interaction so the sensor coil sees the emulating pulses as the indicator of rotational speed. The emulating pulses proportional to the base speed and adjustable to desired levels of variation from the base speed as a reference.
